  • Git per-branch permissions

    We’ve had Git hosting support in Launchpad for a few years now. One thing that some users asked for, particularly larger users such as the Ubuntu kernel team, was the ability to set up per-branch push permissions for their repositories. Today we rolled out the last piece of this work.

    Launchpad’s default behaviour is that repository owners may push anything to their own repositories, including creating new branches, force-pushing (rewriting history), and deleting branches, while nobody else may push anything. Repository owners can now also choose to protect branches or tags, either individually or using wildcard rules. If a branch is protected, then by default repository owners can only create or push it but cannot force-push or delete; if a tag is protected, then by default repository owners can create it but cannot move or delete it.

  • Open Source Contributor Experience

    We will be covering what contributor experience is, how we help the project, the projects we are current working on (if the talk were today: mentoring, automated workflows, new contributor onboarding, communication pipelines, etc.), and how folks can get involved

  • End of the line for Java 8 public updates – Commercial users at a crossroads

    2018 was a year of uncertainties and misunderstandings for the Java world as people struggled to understand the differences between Oracle JDK vs Oracle’s OpenJDK builds vs OpenJDK builds, the costs involved, whether it’s a good thing to jump on the Java release train or not and the list goes on.

    Some Java Champions joined forces to untangle the Java releases and support confusion; they created a Google Doc which summarizes all the changes Oracle is making, as well as the options Java SE users can choose from. Although the most common provider of Java SE implementations is Oracle JDK, there are others out there such as Azul, Eclipse, IBM, Red Hat, Oracle, SAP, and the list goes on. In short, you can still get the Oracle JDK, Oracle’s OpenJDK builds and OpenJDK by other providers for free.

  • How to install go1.19beta on Ubuntu 22.04 – NextGenTips

    In this tutorial, we are going to explore how to install go on Ubuntu 22.04 Golang is an open-source programming language that is easy to learn and use. It is built-in concurrency and has a robust standard library. It is reliable, builds fast, and efficient software that scales fast. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel-type systems enable flexible and modular program constructions. Go compiles quickly to machine code and has the convenience of garbage collection and the power of run-time reflection. In this guide, we are going to learn how to install golang 1.19beta on Ubuntu 22.04. Go 1.19beta1 is not yet released. There is so much work in progress with all the documentation.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
